Skylight Installation and Replacement for Riverbend Homes
Skylights add natural light, but they fail. Most leaks Trill diagnoses on Godfrey roofs trace to skylight flashing rather than the skylight body itself. Old skylights with degraded seals or flashing kits installed by the previous roofer often leak around year 12-15. Trill Roofing installs new skylights and replaces failing ones in Godfrey, Alton, Edwardsville, and the rest of the Riverbend. VELUX, Wasco, and Sun-Tek brands. Fixed, vented, manual-open, and electric/solar models. Flashing kits matched to the roof material and pitch.
What Skylight Work Trill Handles
Skylight services covered:
- New skylight installation: Cut-in on existing roofs. Most efficient as part of a roof replacement, but standalone install is possible.
- Skylight replacement: Like-for-like replacement when the skylight has reached end of life (typically 15-25 years).
- Flashing kit replacement: Many “skylight leaks” are actually flashing failures around an otherwise sound skylight. Trill replaces the flashing kit without replacing the skylight.
- Skylight repair: Cracked glass, seal failure, motor replacement (electric units), or screen replacement.
- Brand options: VELUX (most common, best parts availability), Wasco (commercial-grade), Sun-Tek (budget option).
- Style options: Fixed (no opening), vented (manual or electric), tubular (10-14 inch for closets and bathrooms).
Skylight install timing matters: it is far cheaper to add a skylight during a roof replacement than as a standalone project. If you are replacing your roof within the year and have been considering a skylight, ask about the add-on cost. Illinois IDFPR licensed (#104.020330), fully insured.
